I have exactly the same problem on my Samsung S10. For a second it shows the Adobe Acrobat for Samsung start screen then it gives me only three options, none of which can open a PDF (one of the options is Garmin Connect!?). I don't have any issues opening PDF documents from other sources.
Cannot view my PDF documents
in Evernote for Android Issues (Versions 8.13.3 and under)
